SPOOL OR BOBBIN.

SSPECIPICATION forming part of Letters Patent No. 344,928, dated July 6,1836. Application filed September 24, 1885. Serial No. 178,026. (Nomodel.)

To aZZ whom, it may concern.-

Be it known that I, OSCAR F. VVAII, a citizen of the United States,residing at Springfield, in the county of Windsor and State of Vermont,have invented certain new and useful Improvements in Spools or Bobbins,of which the following is a specification.

My invention is an improvement in wooden spools or bobbins which arere-enforeed by strengthening material let into an annular groove at oneend thereof; and the object of my invention is to utilize wire for thispurpose, and to firmly secure the same to the wood.

In the accompanying drawings, Figure 1 is an end View of a; spool orbobbin which embodies my invention. Fig. 2 is a central longitudinalsection of a portion of the same. Fig. 3 is a side elevation of the wirewith which said bobbin isre-enforced. Fig. 4. is a side elevation of awire wound or braided with a fibrous material, and Fig. 5 is aperspective view of the same cut into suitable lengths and bent intorings for a reenforce.

A designates a spool or bobbin, in one end of which is an annular groovefilled by re-enforce a. This re'enforce is formed of wire, a fibrousmaterial, and cement. I prefer to combine the fibrous material with thewire by first winding or braiding the wire with the fibrous material incontinuous lengths, as shown in Fig. 4. This fibrous material isthoroughly saturated with glue or other adhesive cement. The coveredwire is wound into the form of a helix of any desired length,

and then cut into short sections of about three combined wire, fibrousmaterial, and cement is firmly pressed into the annular groove to formthe re-enforce a. There should be a suf ficient amount of the fibrousmaterial to fill all the interstices within the groove. The portionswhich surround the wire; within the groove in Fig. 2 are intended torepresent the combined fiber and cement. When the cement is properlyhardened, it firmly adheres to the wood and fiber, and binds the wirefirmly in place.

Another manner of forming the reenforce is illustratedin Fig. 5. Thewire is wound or braided in continuous lengths, and then formed intorings, which are placed within the annular groove at the end of thebobbin, one upon the other, so as to break joints, as indicated in Fig.5. Before thus placing the rings within the groove the fibrous materialis thoroughly saturated with cement. The rings thus cemented and placedare firmly pressed, so as to cause thefibrous material to fill theinterstices.

I have herein illustrated and specifically dcscribed two different waysof preparing the combined fiber and wire; but it may be prepared inother ways, and produce substantial] y the same article.

I do not claim, broadly, a spool or bobbin having a re-enforce securedwithin an annular groove at the end of the bobbin, as I am aware thatthe same is old.

I claim as my invention- The herein-described spool or bobbin, having anannular groove at one end filled by a re-enforce composed of wire,fibrous material, and cement, substantially as described, and for thepurpose specified.
